Setup and Installation

Proper installation is crucial for the safe and efficient operation of your water heater. If you are unsure about any step, consult a qualified plumber or electrician.

1. Mounting Options:

The unit can be installed either wall-mounted or floor-mounted, typically under a sink or in other small spaces. Ensure the mounting surface is sturdy enough to support the weight of the unit when full of water (approximately 2.1 gallons + unit weight).

2. Plumbing Connections:

1. Identify the cold water inlet (blue cap) and hot water outlet (red cap) on top of the unit.
2. Connect the cold water supply line to the inlet. It is recommended to install a shut-off valve on the cold water supply line for maintenance.
3. Install the included safety relief valve on the cold water inlet line or as per local codes.
4. Connect the hot water outlet to your fixture's hot water line.
5. Once connections are secure, slowly open the cold water supply valve and allow the tank to fill completely. Open a hot water faucet at the fixture to purge air from the system until water flows steadily.
6. Check all connections for leaks.

3. Electrical Connections:

The unit operates on 110V and requires a 1500W power supply. Ensure the electrical circuit can handle the load. It is recommended to use a dedicated 20-amp circuit with 12-gauge wiring and an appropriate outlet.

1. Ensure the power supply is OFF at the circuit breaker before making any electrical connections.
2. Plug the water heater's three-pin plug into a grounded electrical outlet.
3. Verify that the outlet meets the voltage and amperage requirements.

Operation

1. Initial Startup:

1. After ensuring the tank is full of water and all plumbing connections are leak-free, turn on the electrical power at the circuit breaker.
2. The indicator light on the front panel will illuminate, indicating the unit is powered on and heating.
3. The water heater will begin heating the water to the set temperature. This typically takes 5-10 minutes for the initial heating cycle.

2. Temperature Adjustment:

The heating temperature can be adjusted using the knob on the front panel, ranging from approximately 86°F (30°C) to 149°F (65°C).

• MIN (Low Temperature): Suitable for daily washing or handwashing, caring for skin.
• Medium Temperature: Ideal for washing vegetables and removing residues.
• MAX (High Temperature): Recommended for dishwashing and cleaning oil contamination.

The unit will automatically maintain the set temperature, reheating as needed to replenish hot water.

Maintenance

Regular maintenance helps ensure the longevity and efficiency of your water heater.

1. Draining the Tank:

It is recommended to drain the tank annually, especially in areas with hard water, to prevent sediment buildup.

1. Turn off the power supply to the water heater at the circuit breaker.
2. Close the cold water supply valve to the unit.
3. Open a hot water faucet at the connected fixture to relieve pressure.
4. Carefully open the drain valve (if present) or disconnect the cold water inlet to allow the tank to drain. Be aware that the water may still be hot.
5. Once drained, flush the tank with cold water to remove sediment.
6. Close the drain valve, reconnect the inlet, and refill the tank as described in the 'Plumbing Connections' section before restoring power.

2. Descaling:

In hard water areas, mineral deposits (scale) can accumulate on the heating element and tank walls, reducing efficiency. Descaling may be required periodically. Consult a professional for descaling procedures or if you notice reduced hot water output or unusual noises.

3. Cleaning:

Clean the exterior of the unit with a soft, damp cloth. Do not use abrasive cleaners or solvents.
